Infineon Announces New TV Tuner ICs For Portables

Infineon today introduced its new tuner ICs TUA6041 and TUA6045 specifically designed for portable applications such as laptops, USB dongles and PDAs. Both ICs are claimed to be the industry’s first single conversion tuners operating at a supply voltage of 3V, halving their power consumption and heat dissipation. The TUA6041 and TUA6045 integrate the RF (Radio Frequency) and IF (Intermediate Frequency) functions in one chip improving system reliability and decreasing the footprint area of the tuner IC by around 50 percent to 49 mm?.

Live demonstrations of the new Infineon TUA6041 and TUA6045 will be exhibited at the China Digital Consumer Electronics Component Exhibition in Shanghai (November 22-25, 2005, booth 1CG7).

The supply voltage ranging from 5.5V to 3V allows manufacturers of tuners and end-user equipment to adjust the tuner IC according to the system's power requirements. Power consumption is further reduced thanks to the stand-by mode function while a selectable narrow or wide band Automatic Gain Control improves the TV reception quality. In addition to manual alignment, the TUA6041 features automatic digital alignment by the means of software during basic set-up in the production process - a feature addressing mainly end-user equipment manufacturers as it avoids the manual alignment in their manufacturing process.

Samples of the TUA6041 and TUA6045 are available now. Volume production is planned for the end of Calendar Year 2005.
